There are two main problems I've found with 70s and pre-70s books. One is that the paper is coarser and stickier than more modern books (either because it was made that way or because it has deteriorated) and this makes pages more likely to stick together and double feed.

The second is that the glue appears to be less consistent in how far up into the book it's gone. If you get a page turning in the scanner, then my experience is pretty much that it was stuck or partially stuck to another one.

There are some tricks with this; you can cut a little further into the book, is an obvious one. But when the book is cut look at the cut edges. Sometimes you can see the glued pages as a line. Bend the book. When pages are stuck, you can feel a different sort of resistance. Next you can riffle the pages. I think this may even help the sticky paper syndrome.

My approach (being a geek) has been to write some software which runs the scanner and, having assembled a (large!) tiff file lets you rescan pages which have misfed in the main run. (iaindowns.wordpress.com if you're interested!).

Good luck.
